This development of more than a dozen properties was aimed towards the high specification end of the real estate market. When Ohms and Watts Services ("OWS") was brought in, the site was literally a patch of open ground, from which four separate residential blocks have now emerged.

OWS electricians installed wiring devices in each plot, with their associated conduits, distribution boards and end-user devices. This work extended beyond the limits of each flat, to provide door-entry systems, architectural lighting and security.

An appropriate type of installation was used for each circumstance. Car parking lighting, which illuminates the underground area automatically when a vehicle enters, was incorporated into a DALI (Digital Addressable Lighting Interface) network, whereby bi-directional communication allows central control. Internal lights were interfaced to the low-voltage "SELV" circuits used by the KNX automation system. Switches for roof terraces and gateways, landscaping lighting, patio lights, gate entry illumination, all suitably IP-rated ("ingress-protected" for outdoor use) were linked to armoured-cable external circuits.

Collaborating with the developers, OWS created a KNX automation network in each flat, whilst also managing the conventional, audio-visual and data wiring. Thereby, the standard, high-quality construction of each flat could be made responsive to the personal tastes of the new owners.

Downlighters in each room are programmable to dim to a predetermined level, and can also be manually adjusted for luminance level from every wall switch. The lighting installation provides the choice of whatever combination of dimming and switching from any wall-mounted module, all programmable at the behest of the owner. For example, an "all-off" switch conveniently gives the occupants the luxury of leaving the apartment without having to check every lamp in turn. The opposite is also true: a "welcome-home" switch can activate a selection of lights, with the desired intensity, from a single button.

Lighting is just one of the services integrated under the auspices of the KNX central control. Independent under-floor heating mats in each room (more than one in the larger areas) react to inputs from temperature sensors integrated into the switches and embedded in ensuite walls. The temperature of each room is thereby regulated independently. A switch can also be programmed to turn all circuits to "frost-protection" mode, for use, for example, if the property is left vacant for a period during a winter holiday.

The new owners can benefit from the pre-wired circuits for sound and vision. With cables already embedded in the walls, and extending to each room, there is no need for unsightly exposed conduits or the opening of the wall plaster to bury new wiring. Every room has its set of ceiling speakers, which link to a central location. OWS then installs a music system to the customer's specifications, with potential for surround-sound, home cinema, satellite, DAB radio ... the list goes on.

This can also be integrated with the Internet, to allow streaming of tracks from providers such as Spotify, or album tracks can be enjoyed from a server located in an audio-visual cabinet in the flat. The wiring allows for a keypad to be installed at the entrance to each room, in order to control the music system remotely; these, in turn, are capable of channelling signals from infra-red remote controls, so the central system is always available, wherever the user may be.

The multi-source capability allows different listeners to experience their own music independently of others. Alternatively, another digital source, such as a DAB radio channel or iPod dock, might be listened to by a group of people in another location simultaneously. Internet and satellite television can also be connected to outlets pre-installed in every room. Every permutation is catered for, with a minimum exposure to cables and devices in the living areas.
